ESTIMATION OF AERODYNAMIC ROUGHNESS AND ZERO PLANE DISPLACEMENT USING MEDIUM DENSITY OF AIRBORNE LIDAR DATA
Airborne LiDAR Aerodynamic Roughness Length Zero Plane Displacement Forest
2016/10/14
This paper presents a framework to estimate aerodynamic roughness over specific height (zo/H) and zero plane displacement (d/H) over various landscapes in Kelantan State using airborne LiDAR data. The...
Surface roughness of pyroclastic deposits at Mt. Etna by 3D laser scanning
surface roughness pyroclastic deposits Laser 3D
2015/9/1
The terrestrial 3D Laser Scanning technique has been applied to analyse the surface roughness of pyroclastic deposits on volcanic surfaces at Mt. Etna. This technique allowed the construction of high ...
Basal roughness of the Institute and Möller Ice Streams, West Antarctica: Process determination and landscape interpretation
Antarctica Roughness Radio-echo sounding Ice dynamics Mö ller Ice Stream Institute Ice Stream
2014/5/20
We present a detailed analysis of bed roughness beneath Institute and Möller Ice Streams, west Antarctica, using radio-echo sounding data (RES) acquired in the austral summer of 2010/11. We asses...
Tsunami inundation modelling based on detailed roughness maps of densely populated areas
Tsunami inundation modelling based detailed roughness maps densely populated areas
2010/10/21
An important part within the German-Indonesian Tsunami Early Warning System (GITEWS) project was the detailed numerical investigation of the impact of tsunamis in densely populated coastal areas of In...
Assessing soil surface roughness decay during simulated rainfall by multifractal analysis
soil surface roughness decay simulated rainfall multifractal analysis
2009/11/2
Understanding and describing the spatial characteristics of soil surface microrelief are required for modelling overland flow and erosion. We employed the multifractal approach to characterize topogra...
